"A McGill-led study confirmed that some FRBs originate from neutron stars, based on the polarization and behavior of a detected signal. An MIT-led study further supported this by identifying “twinkling,” indicating a compact emission source. These findings strengthen the case that neutron stars generate FRBs, challenging previous theoretical models. Credit: SciTechDaily.com"(ScitechDaily, Fast Radio Bursts Explained? Scientists Zero In on Their Mysterious Origins)
The FRB source is connected to neutron stars. There is a thing called polarization, which means the neutron star filters other than a couple of frequencies from the radio signals. But that is only one explanation about the fast radio burst, the FRB source. There are models that the FRB forms when plasma rings around neutron stars or black holes impact each other. If those plasma rings rotate in opposite directions that can cause a situation.
The plasma at that point sends very high energy radiation that can be X- or gamma-ray bursts (XRB, GRB). But why not the FRB? Maybe that plasma will impact with a star that orbits the neutron star. That can cause a very high-level energy burst. And that can explain the FRB.
But the more probable explanation is that the neutron star turns upside down. In that case its jet impacts with its plasma ring and the star that orbits the neutron star. That explains why that phenomenon is so hard to predict.
There is also one interesting possibility that can cause the FRB. It's possible. That sometimes neutron star turns upside down. In that case, the jet of the neutron star will impact with its disk and the star that orbits the neutron star. When the jet impacts the star. It raises its energy production to a very high level. Then the star sends plasma impulse to the neutron star's magnetic field.
That magnetic field acts like a gravity lens and focuses radio waves and plasma into one point. And that can explain why the FRB is so powerful. When a radio wave travels through that point it transfers lots of energy into the radio waves. And maybe that explains the power and unpredictable nature of that mysterious high-energy phenomenon.
